Create a template-conversion job
Kicks off a pipeline that applies the target brand template (templateName) to the input PowerPoint (fileId or inputDeck). Returns a callback_id to poll. Counted against the TC_START usage limit.
Subsequent calls in the same conversion lifecycle: poll GET /api/v1/template-converter/status/{callbackId} until the pipeline reaches a terminal state.
Headers
Optional client-generated key (a UUID is ideal) that makes a write request safe to retry. The first request is processed and its response cached for 24 hours; an identical retry with the same key returns the cached response plus an Idempotency-Replayed: true header, so the job is never created twice. Reusing a key with a different body returns 409 IDEMPOTENCY_KEY_REUSED_WITH_DIFFERENT_BODY.
Request body
